WASHING MACHINE.

Application flled March 2, 1926. Serial No. 91,701.

My invention relates to improvements in washing machines, and one of my improvements consists in providing for the tub means for segregating and evacuating sediment during the process of washing articles therein while separating the articles from the accumulated sediment. Another improve-- ment is in supplying a combination .of IOCk" ing dollies adapted to thoroughly shift and agitate articles in the tub at both its upper and lower levels.

-With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes'in the precise embodiment of invention herein disclosed can be made within the. scope of what is claimed without departing from the spirit of the invention. My invention is illustrated-by the annexed drawings, in which Fig. 1 is a vertical axialsection of mywashing machine with parts broken away, Fig. 2 is a top plan thereof with the hinged cover removed and parts broken away, and Fig. 3 is a detail section on a larger scale, showing one of the cups and its port of the lower dolly-carrying separating disk.

The open top tub 1 is preferably constructed of metal such as aluminum and is proveded with a hinged cover 2. The body of the tub is of one piece with a large central bottom circular aperture within which is fitted a. bottom closure 6, which, as with other parts of the machine are preferably castings. The bottom closure 6 is marginally sup.- ported upon an annular supporting shelf and removably secured thereto by bolts 36. From its side walls the bottom of the tub is slightly coned downwardly toward the periphery of the closure 6 and its upper face is preferably shapedwith inclined radiating ribs 39 between which are the radiating troughs 30 to conduct sediment inwardly.

"At the inner ends of these troughs 30 is an annular low ridge 31, and this ridge is apertured radially with inwardly inclined small holes or passages '32 whose inner ends deliver upon the upper face of the eripheral margin of the closure 6. T eradial troughs 30 are relatively shallow and each delivers; into the outer end of one'of the passa cs 32. The closure 6 is downwardly dishe to provide a sump 33 to receive col lected sediment and communicates'witli a. drainage pipe having a valve-controlled terminal faucet.

The outer bottom part 29 is supported on the legs 3. Means are provided for vertical adjustments of the legs, comprising casters whose shanks 4 are mounted in sockets in thelower ends of the legs, both the shanks and the sockets being supplied with alined apertures for insertion of bolts 5 when a desired adjustment is effected.

The closure casting 6 is formed with a centrally raised portion which is axially apertured at 8 to receive the rock-shaft '9, and the latter may be rocked to and fro throughout a desired distance by driving mechanism not shown as this is not claimed n my invention. a

This raised central part of the bottom casting 6 .is carried upwardly centrally through the tub 1 as an axially hollowed conically tapering body 7 which at its upper end hecomes cylindrical and is interiorly fitted with a bronze bearing sleeve 10 for the shaft 9. The upper. end of the shaft 9 is threaded at 18' to take a terminal nut 16 secured thereto also by means of a countersunk setscrew 17. Upon the angularnut 16 an en larged head block 14L is removably fitted at 15. From the block 14 depends a reducfcylindrical part 12' mounted loosely abo the upper part of said fixed part 7. Another and outer sleeve part 19 is mounted around the depending part 12 and secured thereto by means of rivets 13. e sleeve 19 is acasting which is conically enlarged downwardly at 22 to and inte ral with abottom horizontal disk 26. T is disk 26 overlies the bottom closure 6 .and projects also over a portion of the tub bottom 29 nearly to the annular ridge 31. On the parts 1922 are integral radial dollies .2021. The upper face of the bottom disk 26 has integral radial ribs or dollies 23 whose inner ends are integral with the sleeve part 22.

As shown in Figs. 1 and 2, the disk 26 has apertures as shown in Fig. 3 at 28 which efl'ect communication between the interior of the tub above and below the disk, and said 34 to arrest water dashed against it so as to deflect the water to drive over the hood instead of, through the aperture 28, whereby water may move quietly through the aperture 28 without interference.

Within the sump space 33 below said disk 26 sediment may collect, principally by way of the passages 32. In order to prevent violent stirring up of the sediment in the bottom of the sump, I have mounted a division plate 34 just below the delivery lower mouths of the apertures 28 of said disk, which thus divides the sum interiorinto vertically separated parts, t e lower thus kept undisturbed by eddies which may be formed in the upper space under the disk 26 because of the rocking and reversals of direction of the latter. This division late. 34 is circular with a serrated perip eral edge 38 and has-numerous small apertures 37 through which sediment bearing water mayquietly pass. The serrations 38 are circumferentially curved upwardly nearly to the bottom of the disk 26 to thus practically close the space under said disk, but the plate 34 in its marginal part underlies the parts 38 to nearly close the sum space below while permitting passage t erebetween of sediment from the holes 32. The depending hollow rock body 22 has a sleeve part 24 depending below the disk 26 and rockably mounted upon a bronze bearing member 25 fitted upon the central raise portion of the closure 6.

In the operation the dollies are rocked reverselyabout 225 degrees and as both upper and lower sets of radial dollies at 21 and 23 respectively are provided, spaced vertically, articles in the tub are agitated both aboveand below with clearance between said sets of dollies allowing room for sufiicient "water circulation therebetween and thus through the foldings and convolutions of the,articles, but the latter may be driven centrifugally outwardly by the dollies without entanglement o'r tearing, as' the dollies are horizontal and do not project downwardly into the clothes: as in many other machines.

-This centrifugal and loosenin action on the clothes in the tub loosens an discharges dirt outward-1y toward the side wall of the tub to subside and asTsediment flow down the radial bottom troughs 30 to the holes 32 and-under the stationary disk 34 into the sump.

T e disk 34 divides the water under the rocking plate 26 so that-the water in the sump 33 remains still and unaffected by any eddies or swirling of the water-above the-disk 34 caused by the rocking and re-- versing of the disk 26.

The cups or hoods 2728 onthe disk 26 act when the disk rocks back and forth,

by picking up the water in advancing forwardly and pushing it around whereby the water head under the disk is lessened enough as to create a circulation of water by way of the troughs 30 and holes 32 to the sump 33 and through the serrations 38, under the disk .34 leaving sediment in the sump, then the water thus cleaned rises through the disk holes 37 and through the hooded apertures 28 in the rocking disk 26 to complete the circulation.
